    How to Make Irresistible Baked Onions with Asiago Cheese Sauce

    1. Preheat: Set your oven to 400°F (200°C) to create the perfect environment for melting cheese and caramelizing onions.
    2. Slice: Carefully cut the tops off the onions and scoop out the insides to create a cozy little bowl for the cheese sauce.
    3. Sauté: In a skillet, melt butter over medium heat. Add minced garlic and chopped onion scraps, cooking until fragrant and soft, about 5 minutes.
    4. Mix: Stir together the sautéed onions with heavy cream, grated Asiago cheese, thyme, salt, and pepper until combined and creamy.
    5. Fill: Spoon the rich cheese mixture into the hollow onions, packing it generously to ensure every bite is filled with flavor.

    7. Broil: For a golden top, broil the onions for an additional 3-5 minutes, watching closely to prevent burning.
